To all jzowmit may concern.' j Be 1t known that I, JOHN HOHN, a citizenof the United States, vresiding at Baldwin, in'vv the county of Jacksonand Statei o'Iowa,

have invented certain new and useful Im?" proveniente in lWrenches, ofwhich the following is a specification.

My invention relates to improvements in wrenches and the object of myinvention is the provision of a wrench which can be instantly appliedand kadjusted to the object, and in which the adjustment may be obtainedby the use of one hand and with ease and reliability.

Another object of my invention is the provision of a Wrench which willpossess great strength and durability, which will possess merit in pointof simplicity of construction and cheapness of production, and whichgenerally, in every particular, will prov thoroughly eiiicient andpractical.

With these objects in view, my invention consists of a wrench embodyingnovel features of construction and combination of parts for service,substantially as shown, described and particularly defined by the claim.

In order that the construction in detail and the operation or manner ofusing my wrench may be understood, and its features of merit andadvantages be fully appreciated, I invite attention to the accompanyingdrawings, which illustrate a wrench constructed in accordance with myinvention.

Figure l represents a side elevation of a wrench embodying my invention,partly broken away to illustrate detailsv ot construction. Fig. 2represents an edge view lof ,the wrench with a part broken away to showim# portant details of construction. Fig. 3 represents a sectional viewon the line 3 3 of Fig. l, and Fig. 4 represents a perspective view ofthe novel form of sliding member employed in my wrench.

In the drawings: The letter A designates the handle of my wrench, formedwith the shank B, terminating at one end in a rigid j aw C, and formedat each end between the j aw and handle, with shoulders or abutments D,and upon its shank portion provided With a series of openings E. Uponthe shank of the wrench is slidingly mounted the bail or strap-shapedadjustable member F, which is provided with an opening Gin one wall,adapted to register with one of the openings E in the shank, and furtherprovided upon its inner edge with an arm II,- extending .laterally vztndpproviided with a pair of lugs J, between which is mounted the'fulcrumgIQ of the lever L, ormed at titsin- `ner end with the`finger-engaging portion M, `and at its other end with the hook M',adapt ed to it in the opening G of the sliding member and to engage oneof the openings E in the shank, to retain the said sliding member inproper adjustment upon the shank, to retain the lever in engagedposition, I pro vide the spring N, which is disposed between the lugs J,and engages the lever arm. The sliding member thus constructed providesthe open portion P, in which is mounted the fulcrum Q, formed with thearm Q, provided at one end with a jaw Q2, and having its inner end:formed with a finger engaging portion Q3, this construction providingan adjustable aw which is also pivoted in the sliding member. Also thefinger portions of the lever carrying the jaw and the finger portion ofthe adjusting lever are arranged side by side, and thus within easyreach of one hand of the user of the wrench, thus enabling the operatorto instantly adjust the lever with its jaw to suit the size of theobject and at the same time to retain the jaw in proper adjustedposition, and to permit the jaw to be tilted or moved as desired. Toretain the lever with its jaw in proper place, I provide the coiledspring R, which at one end engages the finger-engaging portion of thelever on its underside, and at its other end bears upon the block S,secured within the bail-shaped sliding member.

In using my wrench the rigid aw on the shank is pressed against one sideoi the ob- Aject to be operated upon and the lever o-r movable jaw isbrought into proper position by moving the sliding member until the jawis in engaged position and the sliding member wherein its adjustmentretains the two jaws in proper position, in order that the wrench willgrip the object and permit such object to be turned in the usual manner.

The advantages of my wrench are its ease of application and detachment,its simplicity, durability and cheapness of production, its compactnessand its ease of manipulation and eiiiciency, all of which will bereadily understood and appreciated.

I claim:

The wrench herein shown and described, consisting of the shank having aseries of alining openings and formed with a jaw, a sleeve slidable onthe shank and having an opening adapted to register With one of theseries of openings in the shank, the arm formed at one end with a jawand pivoted in said sleeve and formed at its other end with a fingerpiece, a spring bearing against said arm adjacent the linger piece, anarm on said sleeve extending from the inner edge thereof and formed Witha pair of ears, a lever pivoted between said ears having a 32 hook atone end adapted to pass through the opening of the -sleeve into one ofthe openings of the shank, a finger piece on the other end of saidlever, and a spring for retaining the lever in adjusted position.

In testimony whereof I affix my signature in presence of two Witnesses.
